Re: [Talk-gb-westmidlands] [Talk-GB] Hand-drawn OS maps on Wikimedia Commons
Corner coordinates are now displaying, allowing these to be aligned adjusted to fit. Have fun! Are the configuration files available already somewhere or is there a plan to make them available so users of the maps could just load the maps rather than having to align themselves with the given coordinates. I have just aligned about half a dozen of the maps using MAPC2MAPC and the coordinates posted but it's a long job to do the whole 200 files. Happy to post the files somewhere of the ones I have done. Hi Steven, I've never heard of MAPC2MAPC but it looks great. I posted a comment [1] on the talk-gb-westmidlands mailing list noting that there are KMZ/KML files available on British Library website that include the corner coordinates. It appears that MAPC2MAPC should be able to read these, and then assuming the z/x/y.png output in the OSMTracker is standard TMS this would be exactly what we need to host these online as a map layer (just like Bing or any of the other OS out of copyright maps). Hope this helps. Do you think we can get these hosted on ooc.openstreetmap.org? Regards, Rob p.s. Is there a Linux equivalent of MAPC2MAPC?

Re: [Talk-GB] National speed limit changes
Peter, I say this because the '70 mph' value for maxspeed can only be used case where a road is a dual-carriageway. What about link roads and slip roads? Sometimes they seem to go on for miles without an obvious other carriageway. Yet the correct maxspeed is often 70mph, is it not? How about saying that 70mph can only be valid on a way tagged as one-way?

As such, it seems unreasonable to ask a new mapper to great a situation requiring a court case for every ambiguous section of road in the country to establish if they are dual carriageways or single carriageways. This is why I suggest we use GB:national to indicate that the speed is set by a black/white sign. We could however compromise and suggest 'GB:nsl_dual' where we know if is a dual carriageway, 'GB:nsl:single' where we know it isn't and GB:national where we aren't sure. Alternatively, we could always use 'GB:national' for the maxspeed type and add other tagging to indicate dual carriagewayness, either using 'carriagway=A/B' tag or a relation with type=dual-carriageway or similar. Or.. and this is the simplest approach in the short term as far as I can see which I have been advocating, we can imply dual-carriagewayness by a combining a highway tag with the tag pairs 'maxspeed=70' and 'maxspeed:type=GB:national'. I say this because the '70 mph' value for maxspeed can only be used case where a road is a dual-carriageway. As we get clearer about what constitutes a dual-carriageway or not we then only need to change with speed between 70 mph to 60 mph. We can then also populate approach dual-carriageway tagging on these roads.

I started following your proposal, but I've thought a little more feel that the more involved 'GB:nsl_single' type tag is actually needed I'll be going back through my work over the last couple of days and changing it back. My thinking is; i/. The basis of GB law is that it is up to the individual to know what the law states, and to comply with it. No matter what your SatNav tells you it won't help you when you are standing in a court explaining your actions - the SatNav is a guide only and some maintain that they are unsafe as they distract the driver who may therefore miss the speed limits being displayed. ii/. If you are driving a motor vehicle with very few exceptions you should comply with the law regarding speed limits. iia/. A built up area with street lighting (I'm not entirely sure how you define built up area, and I seem to remember something about the street lights being no more than 200 yards apart) will have a speed limit of 30 mph unless there are signs indicating otherwise, there should be repeater signs at intervals if it is not a 30mph area. iib/. National speed limit signs - the national speed limit has changed during my lifetime. Motorways are fairly simple, and for a car (not towing) it will be 70mph. Two-way roads with a national speed limit sign are also fairly simple, being 60mph for a car (not towing). Dual carriageways - little bit more complex - an island in the middle of the road to assist pedestrians to cross is not sufficient to make it a dual carriageway, but you would need to look at the current case law to help in deciding what exactly is a dual carriageway. I don't think a long length of wide road with the lanes divided by white crosshatch markings on the road, even if this exists for a length measured in miles, counts as a dual carriageway - it needs to have a physical barrier involved. iiic/. A prescribed limit indicated by signs such as '40', '50' etc.. iii/. The current software writers who seem to be using OSM data are mainly wrestling with the basics of navigating a car anywhere in the world but I think steps are being made towards navigation for larger vehicles, and these vehicles are likely to have different speed limits imposed on them in GB national speed limit areas. If they are writing software for navigating a 40 tonne lorry across Europe then the least we can do

Where people quote sources like this one (or more generally quote a URL, rather than a standard source tag), I think they are thinking more in wikipedia terms. Wikipedia tends not to concern itself with database copyrights, as long as the exact wording of a source isn't reproduced. For wikipedia, the source goes to show that the material is not original research. On the other hand, OSM actually prefers original research - a survey is the highest form of source. Incidentally, that means that care needs to be taken in using wikipedia to source OSM; importing from multiple articles may, indirectly import a copyright database.. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Thanks for bringing this to my attention - I'll be sure to check such things more carefully in the future. I can't recall how that source tag came to be there - I can only assume that being one of the first few relations I ever did, I had copied it from another relation and edited it.

Re: [Talk-GB] TfL bus maps as source
Tom The TfL bus maps may not be usable but the timetable data on which they are based are available at traveline.info/tnds under the Open Government Licence. Is that ODBL-compatible or am I missing your point? A note of caution however. This week's edition of the London data includes breadcrumb trails of the track taken between each bus stop. I am not sure that TfL have intended to release this level of detail because of map copyright issues. However if you ignore everything between the mapping /mapping tags, then the rest of the Routelink records, ie the stop to stop links, are what is normally available as Open Data.
